Composite operators near the boundary
Vladimír Procházka, Alexander Söderberg
We use renormalization group methods to study composite operators existing at a boundary of an interacting conformal field theory. In particular we relate the data on boundary oper…
Boundary gauge and gravitational anomalies from Ward identities
Vladimir Prochazka
We consider the two-point functions of conserved bulk currents and energy-momentum tensor in a boundary CFT defined on . Starting from the consistent forms of b…
On the -theorem in the Conformal Window
Vladimir Prochazka, Roman Zwicky
We show that for four dimensional gauge theories in the conformal window, the Euler anomaly, known as the -function, can be computed from a -point function of the trace of th…
The Conformal Anomaly in bCFT from Momentum Space Perspective
Vladimir Prochazka
We study the momentum space representation of energy-momentum tensor two-point functions on a space with a planar boundary in . We show that non-conservation of momentum in th…
Conformal Data of Fundamental Gauge-Yukawa Theories
Nicola Andrea Dondi, Vladimir Prochazka, Francesco Sannino
We determine central charges, critical exponents and appropriate gradient flow relations for nonsupersymmetric vector-like and chiral Gauge-Yukawa theories that are fundamental acc…
On the Flow of Weyl-Anomaly
Vladimir Prochazka, Roman Zwicky
An important aspect of Weyl anomalies is that they encode information on the irreversibility of the renormalisation group flow. We consider, $Δ\bar b = \bar{b}^{\textrm{UV}} - \bar…
= Euler Anomaly from RG-dependent metric-Background
Vladimir Prochazka, Roman Zwicky
We consider supersymmetric gauge theories in the conformal window. By applying a suitable matter superfield rescaling and a Weyl-transformation the renormalisation gro…
On Finiteness of 2- and 3-point Functions and the Renormalisation Group
Vladimir Prochazka, Roman Zwicky
Two and three point functions of composite operators are analysed with regard to (logarithmically) divergent contact terms. Using the renormalisation group of dimensional regularis…
Euler Anomaly Flow from Dilaton Effective Action
Vladimir Prochazka, Roman Zwicky
We consider supersymmetric gauge theories in the conformal window. The running of the gauge coupling is absorbed into the metric by applying a suitable matter superfi…
